    Package        : xvt
    Vulnerability  : Buffer Overflow
    Problem-Type   : local root exploit
    Debian-specific: no
    
    Christophe Bailleux reported on bugtraq that Xvt is vulnerable to a
    buffer overflow in its argument handling.  Since Xvt is installed
    setuid root, it was possible for a normal user to pass
    carefully-crafted arguments to xvt so that xvt executed a root shell.
    
    This problem has been fixed by the maintainer in version 2.1-13 of xvt
    for Debian unstable and 2.1-13.0potato.1 for the stable Debian
    GNU/Linux 2.2.
    
    We recommend that you upgrade your xvt package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
